Abstract:- The rapid transition toward renewable-dominated power systems has significantly
reduced system inertia due to the widespread replacement of conventional synchronous generators
with inverter-interfaced renewable energy resources. This reduction in inertia leads to severe
frequency stability challenges, including high rate of change of frequency and deep frequency
deviations following disturbances. To address these issues, this paper presents a coordinated
virtual inertia control framework that integrates a Redox Flow Battery-based virtual inertia
mechanism with a Grey Wolf Optimizer-optimized fuzzy PID controller. The proposed framework
emulates the inertial response of synchronous generators while providing adaptive secondary
frequency regulation under varying operating conditions. The control architecture, mathematical
foundation, and coordination strategy are systematically discussed, demonstrating the suitability
of the proposed approach for enhancing frequency stability in modern low-inertia power systems.
